"Yes but not after vaccination, assuming you are in the 90%. "
Yes, after vaccination, because it's a lot easier to stop the recipient of the vaccination from becoming ill, that it is to stop the thing replicating.

So that is why it is important that as many people as possible have it. It's the reverse of the claim made about the efficacy of face masks, namely that they only protect others, not the wearer.
